Systems look stable. Buyers ask first.
Software architecture for PE and family offices. We build systems that scale, are documented, and survive technical scrutiny — from sketch to production.
13 years in production. 150+ projects. 100+ public repositories.

Sound familiar?
Portfolio companies rarely fail because the technology is old. They fail because nobody can prove it works.
Nobody can explain the architecture
The system runs, but the documentation is years behind and one person holds the knowledge.
Decisions look arbitrary from the outside
There is no written reason why the stack looks the way it does. A buyer will ask, and the honest answer is a shrug.
Diligence turns into a scramble
Diagrams, licence records and deployment history are collected during the audit, not kept before it.
Every release carries risk
Nobody wants to deploy on a Friday. Releases are manual, slow, and nobody knows what breaks.
What We Do
Deep expertise from software architecture to infrastructure. We implement, deploy, and stay accountable for the outcome.
Software Architecture
We design architectures that scale with your business — not against it. From monolith decomposition to event-driven systems, we find the right structure.
View details →Agentic Systems Development
We design and build intelligent, agent-based systems that leverage LLMs and modern AI to automate complex workflows — and deliver production-ready software.
View details →SecDevOps
Security isn't an afterthought. We integrate security into every stage of your development pipeline — from code review to deployment to runtime monitoring.
View details →Google Cloud
We help you leverage Google Cloud Platform effectively — from architecture design and cost optimization to migration and managed services.
View details →NixOS
Reproducible, declarative, reliable. We help you adopt Nix and NixOS for deterministic builds, consistent environments, and infrastructure you can trust.
View details →Infrastructure as Code
Version-controlled, reviewable, repeatable infrastructure. We implement IaC practices using Terraform, Pulumi, and Nix to give you full control over your stack.

What changed in practice
Numbers from engagements we can describe in detail, with the client named where permission exists.
Hornbach product data: batch jobs replaced by event-driven pipelines, 1M+ products.
Google Cloud cost: €50K down to €15K per month at 99.9% uptime.
Compliance architecture running 100K+ daily transactions across 23 markets.
Regulatory violations in those markets since the framework went live.
Every case is written up in full on the service pages, including what did not go to plan.
The 30-Minute Technical Risk Call
One call, one portfolio company, one clear answer on what we would look at first.
What you leave the call with
- A named technical risk: what in this system would break under scrutiny, and why.
- The first three questions a technical buyer will ask, and what to prepare for each.
- A short written summary within two working days.
- A blunt answer to whether we can help at all.
No slide deck. No proposal. No follow-up sequence.
You speak with Lars Artmann, the founder and principal engineer. No sales team, no handover.
Book the 30-Minute CallFree and without obligation. You get a calendar invite and nothing else.
From first call to handover
Four steps. Each one ends with something written down, so the next person does not start from zero.
- 01
The call
30 minutes. We name the first thing we would inspect and say whether the timing works.
- 02
The diagnosis
One to two weeks. Code, infrastructure and documentation reviewed, with a written report of ranked risks.
- 03
The fix
Delivery inside your systems, with your team, at a scope and fixed price agreed beforehand.
- 04
The handover
Documented and reproducible, so the next team can run it without a phone call.
About
Not a vendor. A technical partner who signs the work.
Artmann Technologies GmbH is an IT architecture firm specializing in Private Equity and Family Office portfolios. We help C-level decision-makers turn technically shaky constructs into a stable foundation with growth potential. We don't just help with the next sprint — we think about the next exit.
Founded in 2024 by Lars Artmann, we bring 13 years of hands-on experience from engagements with Rolls-Royce, Hornbach, NASA, Wolt, and DoorDash — 150+ projects delivered, 100+ public open-source repositories maintained. We implement.
What colleagues say
Named recommendations from the engineers, treasury and product leaders we have worked with.
Lars is a highly talented and dedicated technology consultant with extensive knowledge of cloud technologies. He is always up for exciting challenges and works independently. Lars is constantly developing his skills and doesn't rest until the task is completed.
Lars consistently demonstrated a strong bias for action — he didn't wait around but took the initiative to push things forward. His decisiveness made a real difference to the pace and outcome of our work together.
Lars brings the vision into fine concepts and makes complex solutions way easier and faster to develop. He listens very well and always thinks in a third perspective having great social skills connected to that.
Lars is an outstanding developer with an incredible talent for analyzing and solving software problems. He learns very quickly and can easily integrate into existing projects.
Questions buyers actually ask
The six questions that come up in almost every first call.
What does an engagement cost?
Focused work starts around €1,000; a worst-case, full-year engagement lands around €150,000. Scope decides where a project sits between those poles: after the diagnosis you receive a written scope with a fixed price, so there are no surprise invoices. The first call is free, and it is where every engagement starts.
Is this one person? What happens if you are unavailable mid-project?
Artmann Technologies GmbH is a German limited-liability company, so the contract is with the company, not with an individual. Every engagement is documented as it is delivered, which makes the documentation a deliverable rather than an afterthought, so a competent engineer can continue the work.
Our CTO says the technology is fine. Why bring in an outside architect?
Then the review should confirm that quickly. When the answer is uncomfortable, the timing is what matters: a risk found and fixed now is a repair, while the same risk found by a buyer's advisers during diligence is a price reduction.
Do you implement, or just deliver a report?
Implementation is the point. All six services include building. The results further up this page, real-time product data and a cloud bill cut by 70%, were built, deployed and handed over, not recommended to someone else.
Do you sign an NDA and work inside our systems?
Yes. Work happens in your repositories and cloud accounts under your access rules, read-only where that is possible, without copying production data, and with an NDA in place before the first technical session.
How fast can you start?
The first call goes straight into the calendar, so there is no email back-and-forth to arrange it. Scope, start date and deliverables are fixed in writing before work begins.
Let's find what's broken.
